Australia's top scientific minds have released a new publication to dispel confusion and misinformation about climate change and warn of dire consequences if no action is taken now.

The Australian Academy of Science has launched a new booklet reiterating that man-made climate change is real.

The booklet titled Science Of Climate Change: Questions And Answers warns of the consequences for Australia if no changes are made to address the issue.

Academy president Professor Andrew Holmes said there was a gap between public perception of climate change and reality.

"Therefore we need to communicate with the public efficiently, effectively and convincingly so that they're aware," he said.

"This update, which has been written and rigorously reviewed by 17 of Australia's leading experts in a range of climate-related sciences, provides a clear and balanced account of climate change and its impact on Australia.

"Climate change is not something happening in the far-off future, it's happening now.

Academy councillor and Nobel Prize laureate Brian Schmidt said for many people it was easier to accept the status quo and avoid seriously addressing climate change.

"That's why I think it's very important for the academy to come out and make very clear that you shouldn't do that, that there is a diversity of opinion and this is the best opinion ... and it's pretty clear," he said.
